IIRC it is a small runner single plane. It is definitely the Tarantula series- the precursor the Torker intakes.
Everybody says it is not worth running- maybe marginally better than a stock 4 barrel iron intake, but mine worked pretty well, first on a tired 318 then on a 408 in my '72 demon. the car does have 4.10 gears though, so that helped some. Also, mine was a daily driver, not a strip car.
I ended up switching to an airgap. The butt dyno says it works better, but not by tons. Somebody else can give you better advice about what will be the ticket for low ets in your car.
good luck
